so adding: echo "initrd: Running run-init ..." >>/proc/kmsg || true to the /init script in the initrd and adding: echo "Running mountall ..." >>/proc/kmsg || true to /etc/init/mountall.conf (mountall is the very first job that upstart runs after the run-init switch) This results in the following log at the hang: [ 3.597436] initrd: mounting /root/var/lib/lxc/android/system.img as /root/android/system [ 3.779185] Adding 524284k swap on /root/userdata/SWAP.img.

I'd be open for any ideas here ... http://people.canonical.com/~ogra/touch-image-stats/274.changes has the list of changes for this image ... ciao oli
